| | | | | | | | | | | | | | | | | | | | | | | | | Replace all the occurrences of FIELD_SIZEOF() with sizeof_field() except at places where these are defined. Later patches will remove the unused definition of FIELD_SIZEOF().

* xgbe: constify get_netdev_ops and get_ethtool_opsstephen hemminger2016-08-311-2/+2
| | | | | | | | | | | Casting away const is bad practice. Since this is ARM specific driver don't have hardware actually test this. Having getter functions for ops is really unnecessary code bloat, but not going to touch that. Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S.

* drivers/net: get rid of unnecessary initializations in .get_drvinfo()Ivan Vecera2015-10-161-1/+0
| | | | | | | | | | | | Many drivers initialize uselessly n_priv_flags, n_stats, testinfo_len, eedump_len & regdump_len fields in their .get_drvinfo() ethtool op. It's not necessary as these fields is filled in ethtool_get_drvinfo(). v2: removed unused variable v3: removed another unused variable Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* amd-xgbe: Add receive buffer unavailable statisticLendacky, Thomas2015-10-051-0/+1
| | | | | | | | | Add a statistic that tracks how many times an interrupt is generated for a receive buffer not being available to the hardware which prevents the hardware from being able to DMA the received data.

* amd-xgbe: Fix flow control setting logicLendacky, Thomas2015-05-151-12/+17
| | | | | | | | | | The flow control negotiation logic is flawed and does not properly advertise and process auto-negotiation of the flow control settings. Update the flow control support to properly set the flow control auto-negotiation settings and process the results approrpriately.

* amd-xgbe: Move the PHY support into amd-xgbeLendacky, Thomas2015-05-151-24/+26
| | | | | | | | | | | | | The AMD XGBE device is intended to work with a specific integrated PHY and that PHY is not meant to be a standalone PHY for use by other devices. As such this patch removes the phylib driver and implements the PHY support in the amd-xgbe driver (the majority of the logic from the phylib driver is moved into the amd-xgbe driver). Update the driver version to 1.0.1. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* amd-xgbe: Add additional stats to be reported via ethtoolLendacky, Thomas2015-05-151-0/+8
| | | | | | | | | Add additional/extended statistics beyond what is provided by the hardware to be reported via ethtool. The new stats focus on the calls into ndo_start_xmit and the napi_poll routine. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* amd-xgbe: Allow rx-frames coalescing to be changed anytimeLendacky, Thomas2015-04-091-10/+0
| | | | | | | | | | | | Currently the device must be down in order to update the rx-frames coalescing setting because the interrupt indicator is set in the descriptor data during initialization. Allow this setting to be changed while the device is up by moving the interrupt decision into the descriptor reset function and base the decision off of the supplied descriptor index value.

* amd-xgbe: Fix Rx coalescing reportingLendacky, Thomas2015-03-201-7/+5
| | | | | | | | | | | | The Rx coalescing value is internally converted from usecs to a value that the hardware can use. When reporting the Rx coalescing value, this internal value is converted back to usecs. During the conversion from and back to usecs some rounding occurs. So, for example, when setting an Rx usec of 30, it will be reported as 29. Fix this reporting issue by keeping the original usec value and using that during reporting.

* amd-xgbe: Remove Tx coalescingLendacky, Thomas2015-03-201-4/+2
| | | | | | | | | | | | | | | The Tx coalescing support in the driver was a software implementation for something lacking in the hardware. Using hrtimers, the idea was to trigger a timer interrupt after having queued a packet for transmit. Unfortunately, as the timer value was lowered, the timer expired before the hardware actually did the transmit and so it was racey and resulted in unnecessary interrupts. Remove the Tx coalescing support and hrtimer and replace with a Tx timer that is used as a reclaim timer in case of inactivity.

* amd-xgbe-phy: Use the phy_driver flags fieldLendacky, Thomas2015-03-201-1/+0
| | | | | | | | | | Remove the setting of the transceiver type when retrieving the device settings using ethtool and instead set the transceiver type in the phy_driver structure flags field. Change the transceiver type to be internal, also. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* ethtool: Support for configurable RSS hash functionEyal Perry2014-12-081-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch extends the set/get_rxfh ethtool-options for getting or setting the RSS hash function. It modifies drivers implementation of set/get_rxfh accordingly. This change also delegates the responsibility of checking whether a modification to a certain RX flow hash parameter is supported to the driver implementation of set_rxfh. User-kernel API is done through the new hfunc bitmask field in the ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an index in the new string-set ETH_SS_RSS_HASH_FUNCS. Got approval from most of the relevant driver maintainers that their driver is using Toeplitz, and for the few that didn't answered, also assumed it is Toeplitz.
